Prices are indicative, including IVA, excluding installation. Prices per kWh are calculated based on the listed configuration.
The Tesla Powerwall 3 is the third generation of the world's most well-known batería doméstica brand. The Powerwall 3 integrates its own inversor for the first time, making it a fully-fledged all-in-one system. With 13.5 kWh capacity and an impressive peak power of 11.5 kW, it is one of the most powerful residential systems on the market.
Verdict: The Powerwall 3 is technically impressive but pricey. Ideal for those installing a completely new system (paneles solares + battery) who are willing to pay for the Tesla ecosystem. Less suitable if you already have a good inversor, as you would be paying twice.
BYD is a Chinese battery giant that manufactures both vehículo eléctricos and almacenamiento de energía systems. The Battery-Box Premium series is one of the most installed baterías domésticas in Europe. Its modular design, broad inversor compatibility and competitive price per kWh make it a favourite among installers.
Verdict: The BYD Battery-Box is the workhorse choice of Europe. Not the most eye-catching or innovative, but reliable, affordable and broadly compatible. A strong choice if you already have a hybrid inversor or want a system that virtually any installer can fit.
The Anker SOLIX X1 is Anker's instalación fija batería doméstica, from the well-known consumer electronics brand. The system stands out for its extreme scalability (5 to 180 kWh), smart software and the fact that Anker offers an ecosystem ranging from plug & play to professional solutions. The X1 has rapidly gained ground in Europe thanks to a competitive price-to-performance ratio.
Verdict: The Anker SOLIX X1 is one of the best baterías domésticas available today for European hogares. The combination of scalability, smart software and a reasonable price makes it suitable for both principiantes and large systems. At Home Energy Solutions, this is one of the best-selling systems, and that is not without reason.
EcoFlow made its name with portable power stations and translated that expertise into a fully-fledged sistema de batería doméstica. The DELTA Pro Ultra is the flagship: a modular, powerful batería doméstica with the highest peak power in the consumer segment. The system is aimed at hogares where alimentación de respaldo is the highest priority.
Verdict: The EcoFlow DELTA Pro Ultra is the alimentación de respaldo champion. If full home backup during corte de energías is your highest priority, no other consumer system comes close to its peak power. But you pay a premium for that capability, and in the long run the lower cycle count and shorter garantía make it less cost-effective than competitors.
Huawei is one of the world's largest inversor manufacturers, and the LUNA 2000 battery is specifically designed to work seamlessly with Huawei SUN2000 inversors. The result is an extremely efficient, proven and reliable system that has been part of the European installer network for years.
Verdict: The Huawei LUNA 2000 is the reference standard for installers. If you are purchasing a new complete system (inversor + battery) or already have a Huawei inversor, this is an excellent choice. The 97% efficiency is unmatched. But if you already have an inversor from another brand, more flexible options exist.
Pylontech is one of the oldest players in residential almacenamiento de energía and supplies battery modules to numerous OEM partners. The Force H2 is their high-voltage battery for home use, designed to work with third-party hybrid inversors. It is a no-nonsense battery that scores on reliability and price.

Verdict: The Pylontech Force H2 is the budget king. If you are looking for a reliable battery at the lowest price per kWh and you already have a hybrid inversor (or plan to purchase one), Pylontech is hard to beat on value. It lacks smart software features, but as a pure storage solution it does exactly what it needs to do.
GoodWe is a fast-growing Chinese manufacturer of inversors and baterías domésticas. The Lynx Home U series is their answer to the BYD Battery-Box: a modular, high-voltage battery that works well with GoodWe hybrid inversors but is also compatible with other brands.
Verdict: The GoodWe Lynx Home U is a solid mid-range option that is particularly attractive if you have or are considering a GoodWe inversor. The small modular increments (3.3 kWh) are an advantage over Huawei's 5 kWh steps. An honest, reliable option without frills.
Fox ESS is a Chinese manufacturer focused on affordable almacenamiento de energía solutions. The ECS2900 is a stackable LFP battery that operates in the budget segment. Combined with a Fox ESS hybrid inversor, it offers a complete solution for those seeking the lowest total price.
Verdict: The Fox ESS ECS2900 is the ultimate budget option. If the lowest investment is your priority and you are willing to make concessions on software and brand prestige, you get the most kWh for your money here. Combine it with a Fox ESS hybrid inversor for the lowest total price per stored kWh.
The Anker SOLIX Solarbank 2 Pro is a plug & play batería doméstica that you can connect without an installer. The system consists of a base unit with an integrated micro-inversor and ampliable battery packs. It is aimed at hogares that want to start with almacenamiento de energía quickly and easily, without modifications to the fuse box.
Verdict: The Solarbank 2 Pro is the best plug & play batería doméstica for those who want to get started quickly. Ideal for renters, flat dwellers or homeowners who want to test whether almacenamiento de energía works for them. The P1 dongle also makes it considerably smarter than the average plug & play solution.
Zendure is a relatively young but innovative brand that focuses entirely on plug & play almacenamiento de energía. The SolarFlow Hyper 2000 stands out with advanced software for tarifa dinámica optimisation and a remarkably compact form factor thanks to silicon-carbon anode technology in the latest battery packs.
Verdict: The Zendure SolarFlow Hyper 2000 is the smartest plug & play batería doméstica on the market. If you have a contrato de energía dinámico and want to actively trade on precio de la electricidads, Zendure offers the best software partner. The extremely high cycle count (more than 8,000) also makes it the longest-lasting option.
Recommendation: Anker SOLIX X1 (9.6 kWh) — The balance between price, performance, scalability and software makes the X1 the best all-rounder. With 6 kW power and ampliación options up to 180 kWh, you are also prepared for the future.
Runner-up: BYD Battery-Box HVM (8.3-11.0 kWh) — If you already have a compatible hybrid inversor and are looking for the most competitive price per kWh.
Recommendation: Huawei LUNA 2000 (15-20 kWh) — The 97% efficiency and seamless integration with Huawei inversors make this the top choice for large systems. At 20 kWh, you save hundreds of euros annually compared to a less efficient system.
Runner-up: Anker SOLIX X1 (15+ kWh) — If you do not have a Huawei inversor and want a system that can be expanded further in the future.
Recommendation: EcoFlow DELTA Pro Ultra — With 12 kW peak power, you can literally power your entire home during a apagón. No other consumer system comes close.
Runner-up: Tesla Powerwall 3 — 11.5 kW peak power with integrated inversor. More expensive, but more elegantly integrated.
Recommendation: Fox ESS ECS2900 (8.6 kWh) — The lowest price per kWh on the market. Combined with a Fox ESS hybrid inversor, you have a complete system for less than EUR 4,000.
Runner-up: Pylontech Force H2 (10.5 kWh) — Slightly more expensive but more broadly compatible with third-party inversors.
Recommendation: Anker SOLIX Solarbank 2 Pro — The best combination of hardware (4 MPPT, IP65, ampliable) and software (P1 dongle, app). Ideal to get started.
Runner-up: Zendure SolarFlow Hyper 2000 — Better for those with a contrato dinámico who want to trade smartly. The highest cycle count makes it the longest-lasting plug & play option.
Recommendation: Zendure SolarFlow Hyper 2000 — The software for dynamic charging and discharging based on precio spot EPEXs is unmatched in the plug & play segment.
For instalación fija systems with tarifa dinámica optimisation: consider an Anker SOLIX X1 or Huawei LUNA 2000 in combination with Home Assistant.
Recommendation: Anker SOLIX X1 — Ampliable from 5 to 180 kWh. No other residential system offers this growth potential.
Ideal if you are starting now with 10 kWh but might add an cargador de VE and bomba de calor in five years.
The battery price is only part of the investment. For instalación fija systems, costes de instalación of EUR 400-800 are added on top. A backup box for emergency power costs an additional EUR 200-500. Always factor this into your comparison.
Always check whether the battery is compatible with your existing inversor. A BYD Battery-Box works with virtually any brand, but a Huawei LUNA 2000 is most efficient with a Huawei inversor. The wrong combination can lead to lost functionality or the need for an additional inversor.
Pay attention not just to the duration (years) but also to the capacity garantía. A 10-year garantía with 60% remaining capacity (Huawei, BYD) is less generous than 10 years with 80% remaining capacity (Anker, Tesla). That 20% difference equates to 2 kWh of usable storage on a 10 kWh battery.
The price per kWh is not the full picture. A battery at EUR 300/kWh with 6,000 ciclos is cheaper per cycle than a battery at EUR 250/kWh with 4,000 ciclos. Do the maths:
Always calculate the total cost over the vida útil, not just the purchase price.

Do the maths:
There is no single "best" batería doméstica. The Anker SOLIX X1 offers the best all-round balance for the average family. The Huawei LUNA 2000 is the most efficient. The EcoFlow DELTA Pro Ultra delivers the best alimentación de respaldo. The Fox ESS ECS2900 is the cheapest. The right choice depends on your priorities.
Prices range from EUR 1,199 for a compact 1 kWh plug & play unit to more than EUR 12,000 for a large instalación fija system. On average, you pay EUR 300-700 per kWh of capacidad de almacenamiento. The price per kWh has dropped by approximately 15-20% in 2025-2026.
In principle, no. A batería doméstica performs best within the ecosystem of one brand. The main exceptions are the BYD Battery-Box and Pylontech Force H2, which are compatible with a wide range of third-party inversors.
Most baterías domésticas last 15-25 years with daily use. LFP cells gradually lose capacity: after 6,000 ciclos (approximately 16 years), a good battery still has 80% or more of its original capacity. Zendure even claims more than 8,000 ciclos for their silicon-carbon packs.
Yes. All baterías domésticas in this comparison use LFP technology (lithium iron phosphate), which is thermally very stable. LFP has no thermal runaway risk like older NMC chemistry. All systems comply with EU safety standards (IEC 62619, UN38.3).
Now is an excellent time. Battery prices are at historic lows, devolución del IVAs are still available, and the compensación neta scheme ends on 1 January 2027. The longer you wait, the more net-metered revenue you miss out on. Moreover, lead times and installation waiting times are increasing as 2027 approaches.
